ALTEF Gas Sampling Bags
ALTEF is a proprietary fluoropolymer film developed especially for the Gas Sampling market. ALTEF does not exhibit background levels of DMAC or phenol. ALTEF is chemically inert to most acids, aliphatic and aromatic organic compounds, chlorinated solvents, and alcohols. ALTEF has low VOC background and is suitable for most VOC's and many sulfur compounds. Longer sample storage times than most other bag materials.
ALTEF is not recommended for ketones or esters in high concentrations (>30%) and is not suitable for storing H2S.
Maximum operating temperature: 260 ºF
